I just configured LMCE z-wave lighting together with the Merten "RF-configurator" software and the Merten USB stick. I'll describe it and after I'm sure there are no inconsistencies etc I will wikify it.

WHEN do you need it?The Merten software is very useful to program their own proprietary hardware functions, such as ramp times when turning off dimmers, but also their color and greyscale in-wall control panels. You do not need to do this if you have a few merten RF switches or dimmers, and do not want to use their advanced controls.

WHAT do you need?First, a LinuxMCE supported zwave USB interface. See elsewhere on forum and wiki which ones are good. Merten switches, dimmers, and/or pushbuttons (at least one of these!!). You will also need the Merten software, which requires the Merten USB z-wave stick. This stick is not supported by linuxmce as of yet, due to the fact that Merten is less than forthcoming with information about their USB to RS232 chip. That info, I understand, is essential to get the zwave driver to talk to the Merten stick.

HOW do you do it?Took me a while to figure it out, but it is simple, really . First configure everything to your liking, using the Merten software and USB stick. As always, you will have to transfer control to a pushbutton when you are done. Then, insert the LMCE compatible stick into your core, and you probably need to reload dcerouter at that point. Go to the web config, then to interfaces, then select 'advanced' at the zwave interface. Select 'send command to device'. Select 'download configuration', and once you get confirmation that the command was sent properly, triple-click the Merten pushbutton that has master control. This pushbutton will need to be close to the core. It will then transfer the configuration to the LMCE compatible stick.

Note that you will need two zwave USB sticks, and at least one battery-operated Merten pushbutton. Please let me know if anything is unclear.
